So I'm trying to figure out what to buy. I've been searching flash carts on sites claiming they have support for the most recent 9.9 firmware including the gateway, r4, and sky. I read almost all of the stickies but then came to realize it was all outdated information. Even with a couple weeks to a month there's different updates. By reading the most recent thread titles, I'm reading jargon and troubleshooting for people with their devices. In other words, what should I get?
